Patented Apr. 26, 1938 UNiTED STATES PATENT OFFICE Thomas F. Sexton and John J. Sexton, Baltimore, Md.

Application September 24, 1937, Serial No. 165,578

2 Claims.

The object of the invention is to provide a device for use in conjunction with rubber covered horseshoes whereby their replacement with metal shoes provided with calks during periods of freezing weather may be made unnecessary, the lift plate providing for the use of nail calks directly in connection with the rubber shoe and so positioning the calks of the nails that the calks will engage the surface and prevent slipping; and generally to provide a lift plate which is of simple form and susceptible of cheap manufacture.

With this object in view, the invention consists in a construction and combination of parts of which a preferred embodiment is illustrated in the accompanying drawing but to which the invention is not to be restricted. Practical application may dictate certain changes or alterations and the right is claimed to make any which fall within the spirit of the invention.

In the drawing:

Figure 1 is a bottom plan View of the conventional rubber shoe showing the invention applied in operative position.

Figure 2 is an edge elevational View of the structure of Figure 1.

Figure 3 is a sectional view on the plane indicated by the line 33 of Figure 1.

Figure 4 is a sectional view similar to Figure 3 but in the plane of the nail shank.

Figure 5 is a perspective view of the improved lift plate.

In a conventional rubber covered horseshoe, such as illustrated at if], a metal core is entirely enclosed with a rubber covering which, however, is reduced in thickness at opposite sides of the shoe, as indicated at H, where the nails are ap plied to attach the shoe to the hoof, the lateral recesses thus provided in the shoe serving as clearance spaces for the nail heads.

In bad weather, however, the noise reducing feature of the rubber shoe is of no value and the rubber covering itself can be of little use in preventing sliding on iced or sleety pavements, so that the practice is to remove the rubber shoe and replace it with a metal one, having the necessary non-skid feature. This practice, however entails constant preparation for shoe changing with the attendant expense of maintaining a blacksmith constantly available to make the shoe changes when necessary.

The present invention, however, contemplates the use of the rubber shoe on sleety and icy pave- This anti-skid feature slightly less in height than the depth of the re- 10 cesses I, so that when the nails are used without the lift plate, the lugs are held clear of the ground. When the lift plate is employed, however, its thickness is suificient to cause the lug heads 13 to project to the plane of the undersurface of the shoe, or so close to the plane of the undersurface that normal compression of the rubber under the animal's weight will bring the lug heads into contact with the surface.

The ear l5 acts as a lateral bearing member for the lift plate and when in contact with the inner wall of the recess II will position the nail holes l6 in the lift plate directly over the nail holes in the shoe.

While the ear l5 acts as a lateral bearing member for the lift plate, it can also function as a lug when made of sufficient length to terminate it at or near the undersurface of the shoe, so that when the rubber is compressed, its lower edge will be exposed to the surface to engage the same.

The invention having been described, what is claimed as new and useful is:

1. In combination with a horseshoe having a rubber covering and recesses at the edge to provide clearance spaces for the attaching nail heads, 3

a lift plate seated in a recess, and nails passing through the plate and through the shoe and hav ing lug heads whose lower edges are approximately in the plane of the undersurface of the shoe.

2. In combination with a horseshoe having a rubber covering and recesses at the edge to provide clearance spaces for the attaching nail heads, a lift plate seated in a recess and provided with a lateral ear engaging the side wall of the recess, and nails passing through the plate and through the shoe and having lug heads Whose lower edges are approximately in the plane of the undersurface of the shoe.
